Stahl Launches Hypac Super Functional Crosslinkers For High Performance Packaging Coatings

Waalwijk, the Netherlands, 17 July 2025 – Stahl, the global leader in speciality coatings for flexible materials, has introduced a new range of highly functional carbodiimide crosslinker products specially designed for packaging coatings.  

Hypac™ is a group of patented crosslinkers that enable Stahl customers to manufacture high-performing, durable packaging products without compromising on sustainability or safety. 

Crosslinkers improve coating performance 

Crosslinkers, used for their high levels of reactivity, improve a coating’s tensile strength and resistance to cracks, abrasion, chemicals, water and heat, whilst improving adhesion to the coated material. With the help of crosslinkers, coated products can withstand a variety of climates and experience a much longer life, resulting in lower maintenance costs. 

The range includes conventional isocyanate and aziri-dine-based crosslinkers, as well as more sustainable carbodiimide alternatives, making it versatile for customers’ application requirements.   

Carbodiimide crosslinkers: better for people and the planet 

Stahl’s Hypac™ range includes a variety of carbodiimide crosslinkers, which maintain the high performance of aziri-dine and isocyanate crosslinkers without using carcinogenic, mutagenic and reprotoxic (CMR) materials: Carbodiimides are defined as non-hazardous under the Global Harmonized System (GHS). 

Many carbodiimide Hypac™ products cure at room temperature, are water-based, have a long-lasting pot life and contain zero voltatile organic compounds (VOCs), making them the most sustainable, safe and easy-to-use option for high-performance crosslinking.  

Sustainable solutions without sacrificing quality 

Tested using high-level expertise and equipment at our Centres of Excellence, Hypac™ carbodiimide crosslinkers deliver superior resistance, flexibility, and efficiency, while reducing environmental and health impacts.  

Key benefits of Hypac™ carbodiimide crosslinkers include: 

■ Low toxicity and CMR-free 

■ Suitable for a wide range of end applications 

■ Long pot life exceeding 24 hours 

■ Proven anti-soiling properties 

■ Contributes to lower carbon emissions 

■ Non-yellowing 

■ Very high efficiency (on par with aziri-dines) 

■ Low curing temperature 

■ Strong adhesion properties
